Editor's Note

Some resources list all parts of Rododendrons and Azaleas as poisonous if ingested.

The toxic principal is Andromedotoxin, and symptoms include salivation, watering of eyes and nose, abdominal pain, loss of energy, depression, nausea and vomiting, diarrhea, weakness, difficult breathing, progressive paralysis of arms and legs, coma.

We tend to err on the side of caution in PlantFiles, and the danger notation in the details above is to caution gardeners, parents and pet owners to look further for more information.
